PAVEMENT.

SPECIFICATION forming part Of Letters Patent N0. 425,258, dated April 8, 1890. Application filed September 12, 1889. Serial No. 323,769. (No model.)

To all whom, it may concern.-

Be it known thatl, JOHN J. SCHILLINGER, a citizenaof the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in the. Method of Manufacturing Pavements, of which the following is a specification.

This invention relates to a pavement the nature-of which is fully set-forth in the following specification and claims.

In making the pavement I take fibrous material-'-such as straw, sedge, bamboo, or the like-and expose said material to the vapor of sulphur. This operation can be performed in any suitable chamber, and is kept up until the sulphur-vapors have thoroughly penetrated the fibrous material. terial is then placed in a thin layer into a suitable trough or vessel and a covering layer of melted asphalt or bituminous material poured over said fibrous layer. A second thin layer of fibrous material-is then placed on top of the first layer, and a second asphaltlayer is then applied to cover said second fibrous layer. This operation is continued until the vessel is filled with'the layers of fibrous and A presser is then forced onto the contents of the vessel, so as to firmly compress the fibrous and bituminous layers, whereby the fibers and bitumen become bound together, and the surplus bitumen is forced out of the fibrous material. The contents of the vessel, when cool, are cut into blocks of suitable size. ment, these blocks are placed on any suitable foundation with the fibers in a vertical direc The fibrous ma- To make a pave- I tion, or so that the ends of the fibersare exposed to the wear of the pavement.

Of course the composition can 'be applied not only as a pavement, but wherever it may be useful-as,for example, in roofing, railroad-ties, and'other purposes The sulphur, I have found, has a tendency to prevent melting of the bituminous mate rial. If these blocks are to be exposed to great heat-as, for example, in sunny places in a hot climate-it may be of advantage to treat the composition when completed with sulphur-vapors just as the fibrous material Was treated with sulphur-vapors; but I have found that the treatment of the fibrous material alone with the sulphur-vapors gives satisfactory results. a

What I claim as new,.anddesire to secure by LettersPatent, is I The method herein described of producing pavements, which consists in treating I fibrous material with sulphur and compressing the fibrous material in bituminous material, substantially as set forth. I

2. The method herein described of producing pavements, which consists in treating fi brous 1n aterial with sulphur, compressing the fibrous material in bituminous material, and treating the resultant product with sulphur, substantially as set forth. v

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. ,1 y
